The sun unleashed two major solar storms in a single week this month and more are expected to follow. The most recent X-class solar flare erupted toward Earth, sending a wave of charged particles that have amped up northern lights displays and caused a strong radio blackout for some high-frequency communications systems. Effects on communications were felt within minutes of the … [Read more...]
Do I really need that signal?
We’ve been discussing signals from the perspective of their bandwidth relative to the bandwidth of the receptor and have not considered them from the EMC point of view. RF signal energy can get from the emitter to the receptor by conduction or by radiation. We’ll discuss that later. Regardless of the energy transfer process, using the FCC classification scheme we … [Read more...]

Shielded Radial Choke Series for EMI Input Circuits
Renco Electronics announced that it is expanding its line of shielded radial choke components with twelve new inductance values, ranging from 1.2 mH to 10 mH. These higher inductance values are necessary in some EMI input circuits for switched-mode power supplies. The RL-8054 features a full magnetically shielded design and meets additional space demands at only 7.8 mm in … [Read more...]
Terahertz Signal on Silicon Chip Could Scan for Cancer
Cornell researchers have developed a new method of generating terahertz signals on an inexpensive silicon chip, offering possible applications in wireless data transfer, medical imaging, and security scanning. Terahertz radiation has the potential to carry more bandwidth and eliminate the damaging effects of X-rays, but the expense has always made it commercially … [Read more...]
US Pushes Forward on Public-safety LTE Network
The Public Safety Communications Research Program is on an accelerated schedule to set down rules for the mobile LTE network serving police, fire departments and other public safety agencies across the U.S. The network has not previously had standards in its 80 years. PSCR's job is to find out what first responders need from the network and translate those requirements into a … [Read more...]
